LTE Frequency Bands

LTE support two duplexing modes: TD-LTE : Time Divison Duplexing LTE. Both downlink and uplink transmission takes place at the same carrier frequency, unpaired spectrum, at different time slots. The UL and DL slots are isolated through gaurd period. One merit TD-LTE is UL and DL capacity can be changed […]

Carrier Aggregation in LTE-A

Carrier Aggregation(CA) is one of the most desired feature of LTE-Advanced. In LTE-A aggregation of carriers is used to increase the bandwidth and thereby increase data rates upto 1Gbps. Each aggregated carrier is referred to as Component Carrier(CC), can have BW of 1.4, 3, 5, 10, 15 or 20 MHz. […]
